Cuantificación de as removido mediante el uso de diversos microorganismos aeróbicos en un concentrado de arsenopirita del Cantón Zaruma

Abstract

Several academic projects are being developed to investigate how the presence of As can delay the income of developing countries and affect the sale of extractive materials such as gold, silver, copper, and other metals of interest. To address this problem, several mechanisms have been proposed to reduce the presence of heavy metals that directly affect the value of the metals of interest. However, the implementation of these solutions can generate significant costs for the extractive metallurgy industry and does not solve other problems such as obtaining materials of interest from tailings, wastes containing low levels of metals or refractory metals, and amalgams of heavy metals. The aim is to evaluate mechanisms for transforming arsenic, which is a heavy metal, to increase profitability in the metallurgy industry and comply with current waste standards and regulations. To address this problem, the use of microorganisms as a method of heavy metal degradation is proposed, which is more efficient than other methods and does not cause additional environmental damage. This research focuses on the characteristics of using microorganisms for the degradation of heavy metals.
